Steam is adopted as a sweep gas, presenting efficient H 2 recovery (>91%) while replacing conventionally utilized noble carrier gases that require additional gas separation processes. Hydrogen gas, however, cannot be transported in large amounts due to the limitations in the amount that can be stored per unit volume.

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Summary of the economics of a hydrogen economy.

Recently, c-Si modules have been implemented in solar-hydrogen devices, demonstrating SHE [solar-to-hydrogen efficiency] of 9.7%. As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. Schüttauf et al. Schüttauf et al. Click to enlarge.

Such coatings are presently applied either in a batch or continuous process usually using a variety of highly technical processes including thermal spraying, CVD and, most often, PVD. These coatings were applied using roll-to-roll techniques to pre-coat low cost stainless steel foils, and post-coat after part fabrication.
